How do go about installing fuel system?

that reg. won`t feed 2 carbs out of one side, my last set up wouldn`t feed one 800 holley out of 1 side, had to run each side of the reg. to each carb bowl.
those cute little filters will not feed a hot 600 horse engine, even w/ one on each bowl, don`t know about the return type tho.
hope this will save you some trouble. bob
